This book introduces the basics of cellular and molecular biology on a basic level including detailed explanations and examples. It lays the foundation for a systematic understanding of biology, which is essential in order to handle big data in biomedical research. Comprehension of what is measured, how it is measured and how to interpret results is a precondition for the development of novel therapies against diseases.Interdisciplinary research benefits from versatile approaches to generate and test hypotheses, which may lead to new discoveries. Therefore, it requires a new generation of biologists from diverse backgrounds - and they need this introduction.This book helps students and experts from e.g. computer science, informatics, mathematics, physics, and related fields or even if you are in sales and marketing and want to have a better understanding of the biology behind certain products.
